Abstract: This invention provides a surveillance camera unit that is suited for secure placement in an upper corner of a room, abutting two walls and a ceiling, allowing the day or night surveillance of an entire room with a field of view that captures the scene of the entire floor and all four walls, under bright light conditions and under no-light. The upper corner placement is ideal for minimizing the risk of an observed person grabbing onto the unit or tying something to it, either for purposes of destroying himself, the unit, or the surveillance camera equipment within the unit. The unit is substantially a truncated tetrahedron, with each of the four corners truncated and sealed. A back angle of a few degrees greater than perpendicular of each of the rear walls with respect to each of the other walls of the unit allows it to be mounted snugly within a corner even where the angles of the walls of the room are not square angles.

Abstract: The present invention provides a dual camera surveillance and control system. The system comprises a high sensitivity mono camera with enhanced infrared response, an infrared illuminator array for zero ambient light surveillance, and a color camera that does not need to be enhanced in the infra red spectrum. The system also comprises ambient light level sensing, video signal switching technology and power conversion circuitry. The system combines optimized mono imaging under low or no light conditions with optimized color rendered imaging during high ambient light conditions, with both achieving high quality focus. The dual camera nature of the system is transparent to the user due to the integrated automated control of the system, and allows reduced power consumption, making the system suitable for a wireless, remote, self-contained system that draws power from the ambient environment.
